Antonio, known as the Chameleon, and Teresa Lupi: the first has just been released from prison, after ten long years. She is a young police commissioner. They are two tormented figures: Antonio leaves prison with one fixed thought: to avenge the murder of his family, which he witnessed as a child. Teresa, on the other hand, seems unable to live her life in harmony: her personal relationships are superficial and the only thing that seems to satisfy her is work. The lives of these two characters are soon linked by the common fight against the infamous Don Ferdinando, a ruthless boss who controls the city.
